| Bandwidth | the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second |
| Computing Device | a machine that can run a program, including computers, tablets, servers, routers, and smart sensors |
| Computing Network | a group of interconnected computing devices capable of sending or receiving data. |
| Computing System | a group of computing devices and programs working together for a common purpose |
| Path | the series of connections between computing devices on a network starting with a sender and ending with a receiver |
| IP Address | The unique number assigned to each device on the Internet |
| Internet Protocol | a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device |
| Protocol | An agreed-upon set of rules that specify the behavior of some system |
| Fault Tolerant | Can continue to function even in the event of individual component failures. This is important because elements of complex systems like a computer network fail at unexpected times, often in groups. |
| Redundancy | The inclusion of extra components so that a system can continue to work even if individual components fail, for example by having more than one path between any two connected devices in a network |
| Router | A type of computer that forwards data across a network |
| Packet | A chunk of data sent over a network. Larger messages are divided into packets that may arrive at the destination in order, out-of-order, or not at all |
| Domain Name System (DNS) | the system responsible for translating domain names like example.com into IP addresses |
| HyperText Transfer Protocol (HTTP) | the protocol used for transmitting web pages over the Internet |
| World Wide Web | a system of linked pages, programs, and files |
| Digital Divide | differing access to computing devices and the Internet, based on socioeconomic, geographic, or demographic characteristics |
